Layer always on top

I'm not sure I understand exactly what you mean by always on top but that usually does not stop me from venturing an answer anyway.

If you just want the logo to display on every slide, put it on the slide masters you are using for the project - ( you can access slide masters from the View tab on the main Storyline tool bar).  Notice that there are two types of slide masters - one for the content slides and one for the quiz feedback slides so you would have to add th logo to both these sets of slide masters..  

One other thing, if you really want to item to sit on top of the content, you can add a layer to your slide master and place the logo or whatever on the layer. Then on the slide master page (not the layer ) add a trigger that says show layer when the timeline starts.

Any object that you have on the layer will appear on top of the content on your slides.

Your second answer sounds like the solution I tried, I was kind of hoping it wasn't this as I would need to trigger it on all screens / pop-ups.

What I am trying to do is a little more complex than just a logo on screen, there will be buttons and graphics but is the same principle.

Thanks for your advice.

Storyline will load layers in the order they are called, if you always want a layer on the top you could modify what Nacy reccommends and on every layer add a trigger on timeline start to show your top layer (ensure this is not set to close other layers.

this will just need brute force copying and pasting the trigger to every layer

thanks Phil, just as I thought.

I will just have to be very thorough. 

This is kind of sad that 5 years has passed and i'm stuck with the same problem...

Hello Xavier!

This thread is a bit dated. Perhaps I'm misunderstanding what the need is here, but it sounds like the slides needed to be branded with a logo? 

Creating a custom master slides/feedback slides would not work well for you? Can you share what roadblock you run against when doing so?

I spoke too soon. I see further details of your issue here.

An Example of this issue,

if I have a custom navigation menu and when user click button to show this menu it should always be on top of everything.

Issue
if we have a new layer appears while the menu is opened the content of this layer will be on top of the menu which is not correct
